[0022] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0023] According to the instruction manual Figure 1-2It can be known that when the utility model is used, the personnel adjust the position of a pair of clamping assemblies according to the model or size of the metal die-casting workpiece to be processed. The personnel controls the driving assembly outside the frame 6, and the driving assembly can drive a pair of mounting plates 13 inside the frame 6 to move closer to or away from each other, thereby changing the distance between the clamping assemblies on the pair of mounting plates 13, so that metal die-casting workpieces of different models or sizes can be prevented from being on the clamping assemblies and fixed. Here, distance markings can also be designed on the upper surface of the frame 6 so that the personnel can clearly see the adjusted position to achieve the purpose of rapid adjustment. The markings are not drawn in the figure, but they are easy to understand for those skilled in the art. Compared with the prior art, the utility model achieves the purpose of clamping die-casting workpieces of different models or sizes by adjusting the movement of the clamping assembly and changing the distance between the two. It has a large adjustment range and strong applicability. The driving motor 15 on the support plate 1 drives the limit plate 2 and the frame 6 between the limit plates 2 to rotate and flip, which can drive the die-cast workpiece on the clamping assembly to rotate. The utility model can be rotated at any angle for manual processing by workers, or it can be installed on processing equipment, set horizontally, and processed by processing equipment, and the back side can be flipped 180°. In the utility model, sliders 10 are respectively provided at both ends of a pair of mounting plates 13, and slide grooves 3 are horizontally opened on the inner sides of the center of the inner side wall of the frame 6. The mounting plate 13 is slidably connected to the slide groove 3 through the slider 10, which ensures the stability of the mounting plate 13 and the clamping assembly during the adjustment process.

[0024] Specific adjustment work: the driving assembly includes a double-headed motor 8 with output ends on both sides, a pair of threaded rods 7 with opposite thread directions, a pair of fixed plates 12 and a pair of slide plates 4. The pair of fixed plates 12 are arranged at both ends of the side wall of one side of the frame 6. The double-headed motor 8 is fixedly arranged at the center position of one side wall. One end of a pair of threaded rods 7 is respectively connected to the output ends on both sides of the double-headed motor 8, and the other end is rotatably connected to the side wall of the fixed plate 12. The fixed plate 12 makes the threaded rod 7 rotate stably. A sliding mouth 11 is opened at the position of the frame 6 corresponding to the slide groove 3. A pair of slide plates 4 are slidably connected in the sliding mouth 11. One end of the slide plate 4 is fixedly connected to the slider 10, and the other end is opened with a threaded hole, and is screwed to the threaded rod 7 through the threaded hole.

[0025] During operation, the double-headed motor 8 drives a pair of threaded rods 7 to rotate. Since the slide plate 4 is screwed to the threaded rods 7 through threaded holes, and the slide plate 4 is limited by the slide mouth 11, the rotation of the threaded rods 7 can drive the slide plate 4 to move horizontally. The movement of the slide plate 4 can drive the slider 10 and the mounting plate 13 connected to the slider 10 to move. Since the threads on the pair of threaded rods 7 are in opposite directions, the mounting plates 13 on both sides move toward or away from each other, thereby achieving the purpose of adjusting the distance. The adjustment method is simple and stable.

[0026] The clamping assembly includes a fixed splint 20, a movable splint 18, a lower profiling plate 9, an upper profiling plate 19 and a cylinder 14. The fixed splint 20 is fixedly arranged at the bottom of the inner side wall of the mounting plate 13, the lower profiling plate 9 is detachably arranged on the fixed splint 20, the cylinder 14 is fixedly arranged at the center position of the bottom of the mounting plate 13, and the telescopic end passes through the mounting plate 13 to the upper part, the telescopic end of the cylinder 14 is fixedly arranged with a connecting plate 17, the movable splint 18 is fixedly arranged at the bottom of the connecting plate 17, the upper profiling plate 19 is detachably arranged at the bottom of the movable splint 18, and the upper profiling plate 19 corresponds to the lower profiling plate 9 up and down.

[0027] During operation, the vertical movement of the telescopic end of the cylinder 14 can drive the connecting plate 17 and the movable splint 18 to move vertically. First, the cylinder 14 drives the movable splint 18 and the upper profiling plate 19 to move upward, and the personnel place the die-casting workpiece on the lower profiling plate 9. Then the telescopic end of the cylinder 14 is lowered to drive the upper profiling plate 19 to press the die-casting workpiece, and the lower profiling plate 9 is used to press the workpiece tightly, which improves the subsequent processing accuracy. In addition, the upper and lower profiling plates 9 are detachably connected to the fixed splint 20 and the movable splint 18 respectively, and can be replaced according to the model of the die-casting workpiece. It has strong applicability and is also fully prepared for stable clamping. The screw 21 can be used here to fix it.

[0028] Of course, a pin 5 can also be set on the upper surface of the lower imitation plate 9. The pin 5 is set according to the position of the mounting hole or slot of the die-cast workpiece. During installation, the pin 5 can be inserted into the mounting hole or slot, so that the upper imitation plate 19 and the lower imitation plate 9 can be pressed and fixed to the workpiece more firmly.

[0029] In addition, a rotation limiter 16 is provided between the limiter plate 2 and the support plate 1 to ensure that the limiter plate 2 drives the frame 6 and the mounting plate 13, the clamping assembly, and the die-casting workpiece to rotate more stably.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
